At absolute temperature T a black body radiates its peak int

At absolute temperature T, a black body radiates its peak intensity at wavelength lambda At absolute temperature 2T, what would be the wavelength of the peak intensity?

Solution

For a particular black body, accoring to wein law

T=Constant

When Temperature equal to 2T,

(2T)= constant . this is possible only when =/2

/2 (2T)= T= constant

Answer :=/2
